MOE/C5 D Patented Aug. 18, 1931 UNITED STATES MAURICE DUCASSE, OF SANFRANCISCO, CALIFORNIA EXTRACTOR Application filed December 13, 1927.Serial No. 239,637.

The present invention relates to improvements in machines for extractingliquids by centrifugal force and more particularly to such machines asare used in laundries, and other washing and cleaning establishments forremoving water or other liquids from' laundry, etc.

Machines of the character described usually consist of a cylindricalextractor basket adapted to contain the laundry from which the liquid isto 'be extracted. The basket is usually provided with perforated wallsand mounted upon the upper end of a vertical shaft which is rotated byany suitable means.

7 In the more preferred types of machines the rotating means is in theform of a motor mounted directly on the shaft. Due to the unevendistribution of the weight of the laundry contained in-the basket, theshaft and basket must be permitted gyratory movementuntil the masscenters itself and this is usually provided for by a flexible support orbearing for the shaft. The flexible supporting means for the shaftconsists of a resilient meanscapable of yielding laterally and axially.

The main purpose of the present invention is to provide a resilientsupporting means for the shaft' and basket which will provide thedesired flexibility for the gyratory movement of the extracting basket.

The mounting and supporting means of this invention is arranged so as toprovide a free, floating effect for the shaft with the use of a simpleandinexpensive arrangement, which after one installation will providethe desired flexibility over a long period of time without requiringadjustment or attention.

With the above mentioned and other objects in view, the inventionconsists in the novel 0 construction and combination of partshereinafter described, and set forth in the claims hereto appended, itbeing understood that various changes in the form, proportion, size andminor details of construction within the scope of the claims may beresorted to without departing from the spirit or sacrificing any of theadvantages of the invention.

Referring to the drawings:

Fig. 6 represents a cross sectional view taken through the mounting andsupporting means shown in Fig. 1.

The embodiment of the invention shown in detail in the accompanyingdrawings includes, a cylindrical casing 1, mounted on a hollow pedestal2, adapted to be secured in any suitable manner on a foundation indi- 70cated at 3. Mounted within the casing 1 and arranged for rotary andgyratory movement therein, is a cylindrical extractor basket 4 hav-' inga perforated cylindrical wall 5, closed bottom wall 6, and being open asat 7, on its 75 upper side so that wet laundry maybe packed therein.This basket is secured upon the upper end of the vertical shaft 8 of amotor 9, the motor being disposed within the hollow pedestal 2. Themotor is provided on its 30 lower side with a depending sleeve or socket11, which provides for the mounting of the motor upon the resilientsupporting and mounting means 12, to be hereinafter described. Theresilient mounting and supporting means 12 serves as a flexible supportfor the motor 9, shaft 8, and basket 4, permitting these elements tohave a gyratory movement during the operation thereof. A suitableelectrically or mechanically operated brake mechanism 13 is mounted onthe motor casing and cooperates with the shaft 8 to stop the basket 4from rotating.

An annular buffer plate 14 is mounted on the lower part of the casing 1,and the shaft 8 extends through the center of the opening 15 in saidplate. Surrounding the shaft 8 is a sleeve 16 having an annular rubberbumper strip 17 mounted thereon so that in case of extreme lateral orgyratory movement of the shaft, said bumper strip will engage againstthe sides of the opening 15 and thereby limit the said movement of theshaft. The casing 1 is provided with a suitable fluid outlet 18. 5 Theresilient supporting means 12 is made up of a cylindrical casing 19having an integral upper wall 20 from the outer perimeter of which anannular flange 21 extends laterally, said flange being bolted as at 22onto the lower part of the pedestal 2. The casing 19 is extended into adepression or well 23 formed in the foundation 3. The bottom of thecasing 19 is closed by a plate 24 secured in place by fastenings 25.Extending from a point within the casing .19 and upwardly through anopening 26 in the upper wall 20, is a supporting stud 27 which isreceived in the depending socket 11 on the motor, there being a setscrew 28 for securing this supporting stud 27 in place. The stud 27 isgiven a free, floating support in the casing by the use of a resilientmeans as shown in Fig. 1, comprising a solid rubber block 29 ofcylindrical form, which fits snugly within the casing. The stud 27 isembedded in the rubber block 29. An annular flange 30 is formedintegrally with the stud intermediate the ends thereof, and is moldedwithin the rubber block centrally of the upper and lower sides 30thereof, the outer perimeter of the flange 30 being disposed close tobut spaced inwardly from the outer perimeter of the block. A pluralityof openings 31 are provided in the flange so that when the rubber blockis vulcanized upon the stud and flange, a rubber bond will be formedthrough these openings. To provide for regulating the tension of therubber block, a false bottom 32 is mounted in the casing 19 against theunder side of the rubber block, and is adapted to be raised or loweredby means of adjusting screws 33 extending downwardly through the upperwall 20 and rubber block into screw threaded openings 34 formed in thefalse bottom 32. Adjustment may be made when it is necessary tocompensate for wear on the parts of the mounting, it @ing possible toincrease the tension to compress the'rubber block as desired, bytightening of the screws 33. By moving the'false bottom it is possibleto vary the tension'of the compression of the rubber block to thusregulate the position of the motor and basket to properly center thesame in operating position. The stud 27 constitutes the sole means ofsupporting the motor 9, shaft 8, and basket 4, and as said stud is givena free, floating support in the rubber block, a durable, substantial yetflexible, supporting of the rotary shaft, motor and basket are providedfor. This will permit of the necessary gyratory movement of the basket,shaft and motor until the entire mass centers itself. The location ofthe motor on 65. the lower part of the shaft provides for quickercentering of the shaft and aids in the balancing of the machine as awhole.

If desired the rubber block may, as shown, be made up of a center coreof soft rubber, the adjacent'cores being of less soft rubber, and theseveral cores being vulcanized together. The rubber block, thoughvulcanized so as to be comparatively soft, has suflicient body toproperly support the weight of the motor and basket, and also has theflexibility necessary to permit of free gyratory movement.

As shown in Figs. 2 and 4, the modified form of resilient supportingmeans, comprises a supporting stud 35, having a lateral annular flange36 corresponding to the flange 30, said stud being mounted in acylindrical casing 37 corresponding to the casing 19. The resilientmeans for providing the full, floating support ffor the stud 35, in thisform of the invention comprises a plurality of helical coil springs 38mounted on opposite sides of the flange 36 between the top wall 39 andbottom wall 40. v

As shown in Figs. 3 and 5, the modified form of the invention comprisesa stud 41 having a flange 42, being mounted in a casing 43 correspondingto the casing 37. Leaf springs substantially cross shaped and designated44, are mounted in the casing and engage between the top of the flange42 and top Wall 45, also between the bottom of the flange and bottomwall 46. These cross shaped leafthe invention provides the full,floating action as does the mounting in the other forms.
